A train moves from one station to another in 2 hours time. Its speed-time graph during this motion is shown in the figure. The maximum acceleration during the journey is
A
140 km h–2
B
160 km h–2
C
100 km h–2
D
120 km h–2
Answer
160 km h–2
Explanation
Solution
Maximum acceleration means maximum slope in speed –
time graph.
that slope is for line CD.
So, amax slope of CD
= 1.25−1.0060−20=0.2540=160kmh−2.
